Avengers 2: Age of Ultron Star James Spader Talks Playing Ultron: 'He is Really Crazy'

Voice of the evil robot Ultron talks about playing the character in the movie

The first trailer for Joss Whedon's Avengers: Age Of Ultron, was unveiled earlier in the week, which gave us the first proper look at the character of the movie's villain Ultron.

James Spader who plays the voice of the Avengers 2 villain, dished about playing the character in the movie.

"There's a humorous aspect to him", he told the Total Film magazine, adding that "in many ways he's a child, because he's a brand- new being who's just come to be. And yet, through artificial intelligence, he has an incredible capacity for knowledge. So he's a very powerful, smart child."

Spader also cautioned that his character might prove to be a challenge for the superhero team, "Ultron takes abrupt turns in scenes. Red isn't psychopathic, but Ultra is. Yes, he is psychopathic. He's really crazy".
